This invention pertains to improvements in presses and moreparticularly to that type set forth in United StatesLetters Patent to Anderson Nos. 731,73 l, 731,735, and 731,737 dated June 23,1903, wherein there is shown a shell with a series of, separated screws mounted therein,which screws feed the ma; terial lengthwise'through the shell, compress the same and forcethe liquid content, such as oil and the like, thereirom-.- WVorking in conjunction with the outlet of the press," as shown in the patents above referred to, means is provided for retarding'the outflow and causing the materialto be held in the press or shell for the requisite period of-time.

The, presentinvention relates more particularly to the means employed for regulating the, discharge from the press and takes the placeof the cone construction shown inyPat ent 731,734, or the head, shell or casing G of Patent 731,735.. 7 r i 1 Under the [present invention, the choke, as it may be termed, at the discharge end of the press is. stationary in so far as any rotary movement, is concerned though 1 it is adjustable to vary itseffectiveness with relation to the discharge of the material and such adjustment maybe effected while the machine is in operation, whereas under the old construction where the cone was I employed, it was necessary to stop the machine when adjustment was to be brought about. Furthermore, with the stationary choke of the present case less friction obtains between the-choke and'the pressedi cake being discharged from the expeller, with the result that the-,cake is lighterin color, which is a desirable feature; Under the old construction where the cone revolvesand the cake, is

I forced 'thereover, the cake becomes hot on accountof the frictiomproduced 'by 'revolving the cone under the QXtrem-pressu-rewhich obtainsin presses of this type;';;Furthermore, by v the present construction the press isneasier to repair, inasmuch as new-parts can be installed without disma'ntlingthe ex: peller, which dismantling was necessary under l -the-.old coneconstruction, 1Again, the presentchoke materially reduces the amount of machinery andgearsreqnired atithe: dis;

charge end of the expeller over that which obtained under the old construction, or at least under the old commercial form, where the cone was employed. I

Furthermore, the present structure eliminates the cone point and discharge collar with its attendant tendency to leak liquids under cone point and outside of discharge collar as in older forms of presses. In addition to the constructional advantages above set f0rth, it has been found that better extraction is efiected and a gain as high obtains over the olderforms. v

v =The invention is illustrated in the annexed drawings wherein, v,

Extending through the,sl1e1lisashaft 3 surrounded by a tubular sleeve-or member 4. Said shaft and sleeve carry the worms, one ofwhioh is shown at 4*, in the shell of th'eflpress and'act upon the material vto break up and compress the same,-

expressingatheoil therefrom which flows outwardly, betvsr,eenthespaced;bars l- .Ls; r

boss or enlargement 9 through which the members 8 and 4 extend in spaced rela tion. The inner face of the casting 5 is so formed as to receive an inner jaw guiding member of the form best shown in Figure 42. Said member is circular in outline having acentralbore 11 and an outwardly extending projection 12 which is diametrically cut awayasat 13 and l-forming guides-for the jaws which enter said cutaway portions. This block or guide member extends into an opening formed in the inner face of the casting 5 and is secured theretoin any suitable manner as by machine screws 15; as shownin Figures 2 and 3. i A second guide block 16' L is secured to the casting 5 opposite the guide block 10 and in spacedrelation thereto. .Said block, as will be seen upon reference'to Figure 5, is provided withtwo diametrically disposed guideways'l'? and 18, which guideways,

suffice for all and the parts are lettered the when the parts arein their assembled positi'on, stand at right angles to the guideways 13 and 14in the block'lO. There is thus produced in the structureat the outlet or discharge opening for the cake four guide ways which stand in line with the respective guideways 8 formed in the element 5.

' -Mounted in each of the guideways 8 are slides, eachslide carrying at its inner end a jaw, which jaws extend through the guideways 13 and 14c and 17j'and18, respectively. Inasmuch as the slides and jaws, and the means for actuating or positioning the jaws with reference to the sleeve 4, are alike in form and operation, a description of one will same throughout. 7 i

The slides'are shown in detail in Figures 6 and 7. They may be said to comprise a rectangular body 19, into the upper end of which is threaded a jack-screw 20. The upper "portion of said screw has secured to'it a hand wheel or capstan member 21, the upper larger portioncof the screwfor that 'dee noted by 22, passes through a threaded nut yr 23 whichis'securely bolted to thejcasti-ng 5.

The lower portion of the jack-screw issmaller m dmmeter than the upper 'portionwhich' rialwithin the'fshell; a ca'sting mounte'di at passes through the nutand, while-threaded in the samedirectionas the upper part, the threads, are closer together. In ;practice the upper: portion has been provided with three threads perv inch "while thelower portion has four threadsperinch. a By this arrangement rugged threads maybe utilized'-and ,al-firie-inber 10 or 16 and the bottom of the guideway formed in the oppositemember. o To the outer end of the projection .jaw being arcuate' in outline and beveled transversely or beveled outwardly from the outer face toward thejnner face thereof. It will thus be seen that the jaws may be moved inwardly or outwardlyindependently of each otherand toward and from the sleeve member'4to provide a choke of the proper si ze for the particular material-undergoing treatment. The-inner edges of-the jaws may be caused to 'closelyapproach the sleeve 4 and thus effect a greater retardation of the'dis charge ofthe material than would be the case if the jaws were; retracted by'turning the jack-screws outwardly; v a

The guideways 8 will preferably'be bab= bitted as at 27. The guide plates 10 and 16 will be formed of hardened steel or other ap-' propriate metal and the jaws-25 willalso be formed of hard steel;

The jaws, as above noted, tend to restrict the outflow of the c'akewhich, after it passes them, passes through the cylindrical bore of the member 16 and outwardly through the member 9; r 7

What is claimed is:

3. In a press, the combination of a shell; a shaft extending through and outwardly from the same; means sustained from the shaft for exerting pressure upon the material within the shell; a casting mounted adjacent the end of the shell, said casting having a central opening formed therein and likewise provided with a plurality of guideways extend- 7 ing radially from said opening in spaced re-. lation; a guide block secured to the inner face of the casting in line with the end of the shell,

said block having a central opening and laterally extending guideways aligning with certain of the adjacent guideways formed in the casting; a second guide block mounted in the inner face of the casting, said second block having guideways formed therein which align with the corresponding vways formed in the casting; a slide mounted in each of the guideways of the casting; a jaw secured to the inner end of each slideway, said jaws being so arranged as to pass through the respective ways formed in the guide blocks; a nut secured to the casting at the outer end of each slideway; and a screw threaded into the nut, the inner end of the screw being likewise threaded and passing into a threaded openingforrned in the outer end of the adjacent slide, the threads upon that part of the screw which passes into the slide being greaterin number per inch than those formed upon that portion of the screw which take into the nut.

In testimony whereof I have signed name to this specification.
